Jo-Philipp Wich eb02b887ff package: fix segfault of iwinfo.scanlist("radio0"). ... This is a bug revealed in r41830. First, the static variable `char nif[IFNAMSIZ]` of nl80211_phy2ifname() would be zeroed out if the argument is "wlan0" or the like. This will happen in the following call stack. nl80211_get_scanlist("radio0", buf, len); nl80211_phy2ifname("radio0") // return static var nif with content "wlan0" nl80211_get_scanlist(nif, buf, len); // tail call nl80211_get_mode(nif); nl80211_phy2ifname(nif); // zero out nif Later we try nl80211_ifadd("") which was supposed to create interface "tmp.", but that won't happen because nl80211_msg() will put an invalid ifidx 0 to the nlmsg. Then iwinfo_ifup() and iwinfo_ifdown() would fail and happily nl80211_get_scanlist() returned 0 and left *len undefined.
